What happened
The non-certificated pilot departed on a Title 14, CFR Part 91, local area personal flight in an experimental light sport homebuilt airplane. A witness reported seeing the airplane flying about 100 feet above trees before the engine noise increased, and the nose pitched down. The airplane subsequently descended nose first into dense woods. The pilot’s flight instructor reported to the NTSB that he had given the pilot 19.2 hours of flight instruction, but the pilot had not progressed to a point where he could endorse him for a solo flight. He said that the pilot routinely struggled with pitch control during takeoff, landing, or when engine power was increased or decreased. Examination of the airplane did not disclose any preimpact mechanical malfunction. Given the lack of mechanical deficiencies with the airplane's engine or flight controls, in conjunction with the witness and the flight instructor’s statements, it is likely the pilot failed to adequately maintain control of the airplane while maneuvering.
